Can anyone explain Laravel 5.2 Multi Auth with example

After lots of digging and lots of questions & answers I have finally managed to work Laravel 5.2 Multi Auth with two table, So I'm writing Answer of my own Question.

How to implement Multi Auth in Larvel 5.2

As Mentioned above. Two table admin and users

Laravel 5.2 has a new artisan command.

php artisan make:auth

it will generate basic login/register route, view and controller for user table.

Make a admin table as users table for simplicity.

Controller For Admin
app/Http/Controllers/AdminAuth/AuthController
app/Http/Controllers/AdminAuth/PasswordController
(note: I just copied these files from app/Http/Controllers/Auth/AuthController here)

config/auth.php

//Authenticating guards
'guards' => [
    'user' =>[
        'driver' => 'session',
        'provider' => 'user',
    ],
    'admin' => [
        'driver' => 'session',
        'provider' => 'admin',
    ],
],  

//User Providers
'providers' => [
    'user' => [
        'driver' => 'eloquent',
        'model' => App\User::class,
    ],
    'admin' => [
        'driver' => 'eloquent',
        'model' => App\Admin::class,
    ]
],  

//Resetting Password  
'passwords' => [
    'clients' => [
        'provider' => 'client',
        'email' => 'auth.emails.password',
        'table' => 'password_resets',
        'expire' => 60,
    ],
    'admins' => [
        'provider' => 'admin',
        'email' => 'auth.emails.password',
        'table' => 'password_resets',
        'expire' => 60,
    ],
],  

route.php

Route::group(['middleware' => ['web']], function () {
    //Login Routes...
    Route::get('/admin/login','AdminAuth\AuthController@showLoginForm');
    Route::post('/admin/login','AdminAuth\AuthController@login');
    Route::get('/admin/logout','AdminAuth\AuthController@logout');

    // Registration Routes...
    Route::get('admin/register', 'AdminAuth\AuthController@showRegistrationForm');
    Route::post('admin/register', 'AdminAuth\AuthController@register');

    Route::get('/admin', 'AdminController@index');

});  

AdminAuth/AuthController.php

Add two methods and specify $redirectTo and $guard

protected $redirectTo = '/admin';
protected $guard = 'admin';
public function showLoginForm()
{
    if (view()->exists('auth.authenticate')) {
        return view('auth.authenticate');
    }

    return view('admin.auth.login');
}
public function showRegistrationForm()
{
    return view('admin.auth.register');
}  

it will help you to open another login form for admin

creating a middleware for admin

class RedirectIfNotAdmin
{
/**
 * Handle an incoming request.
 *
 * @param  \Illuminate\Http\Request  $request
 * @param  \Closure  $next
 * @param  string|null  $guard
 * @return mixed
 */
public function handle($request, Closure $next, $guard = 'admin')
{
    if (!Auth::guard($guard)->check()) {
        return redirect('/');
    }

    return $next($request);
}

}

register middleware in kernel.php

 protected $routeMiddleware = [
    'admin' => \App\Http\Middleware\RedirectIfNotAdmin::class,
];

use this middleware in AdminController e.g.,

namespace App\Http\Controllers;

use Illuminate\Http\Request;

use App\Http\Requests;
use App\Http\Controllers\Controller;
use Illuminate\Support\Facades\Auth;

class AdminController extends Controller
{
    public function __construct(){
        $this->middleware('admin');
   }
public function index(){
        return view('admin.dashboard');
    }
}

That's all needed to make it working and also to get json of authenticated admin use
Auth::guard('admin')->user()

Edit - 1
We can access authenticated user directly using
Auth::user() but if you have two authentication table then you have to use

Auth::guard('guard_name')->user()  

for logout

Auth::guard('guard_name')->user()->logout()

for authenticated user json

Auth::guard('guard_name')->user()
